Hold'em Street Descriptions
When playing Hold'em or Omaha, the first street you will play is the preflop action. During preflop action, no community cards are dealt. When the preflop action is over, we will play the next street: the flop. The flop is the only street on which 3 community cards are dealt. If necessary, there will be the third street, the turn. On the turn, 1 community card is added to the flop. After the betting round, there is the river, the last street. On this street the last community card is revealed. If necessary, after that we will go to the showdown.
